A lower felt washer 19 is disposed in the lower portion of the bushing 62 and a metal washer 89 is interposed between the lower roller bearing structure and the upper side of the felt washer I9. I

A frusto-conical lock washer BI engages in the annular groove 82 formed in the lower portion of the bushing 62 and holds the lower Washer 79 against downward movement.

A grease cup 83 is threaded into the bushing 62 between the two roller bearing members so that those members may be properly lubricated. The shaft 6| has fixed on the lower end thereof a beveled gear or pinion 84, the gear 85 being formed with a hub 65 which is adapted to bear against the lower end of the inner race 12. The gear 84 is held against rotation by means of a key 86 and a nut 81 is threaded on the shaft 5|. The gear 84 may be adjusted endwise by means of the nut 8'! so that any wear in the roller bearings may be readily taken up. The gear 84 meshes with a beveled driving gear 88 which is fixed on the shaft 31 by means of a key 99. The

gear 86 is held against endwise movement in at least one direction, which is the direction of the strain applied thereto, by means of a locking ring 99 which engages in an annular groove 9| formed in the shaft 31.

A gear housing generally designated as 92 engages about the gears 84 and 8B and also provides a means whereby the frame bars 26 and the bearing bushings 39 will be held against lateral strain or bending. The housing 92 is formed of complementary upper and lower substantially ovoidal housing members 93 and 94, which at their outer ends are formed with flanges 95 engaging in annular grooves 96 which are formed in the bearing bushings 36. The housing 92 is formed with an upwardly projecting bushing 91 within which the reduced lower end 98 of the bushing 62 engages.

The shaft 6| has fixed adjacent the upper end thereof an agitator tube or sleeve 99, the sleeve 99 having a bushing I99 fixed in the upper end thereof which is adapted to be secured by suitable means to the shaft 6| above the upper end of the tube 56. The tube or sleeve 99 has fixed thereto a plurality of agitator blades IIlI engaging within the tank 5| so that the insecticide will be thoroughly agitated with the rotation of the shaft 6|.

A bearing bushing I62 is carried by the top member 55 and a roller bearing I63 is disposed in the bushing I92 and engages about the upper end of the sleeve or tube 99. A crank I04 is fixed on the upper end of the shaft 6| and the crank I64 has secured thereto, as shown in Figure 5, a crank pin I65 which is formed with a ball member I66. The ball member I66 engages in a ball socket I 91 which is carried by a piston rod I98 which is slidable through a gland I09. The piston rod I68 has fixed thereto a piston III! which is slidable in a pump cylinder III. The cylinder I II includes a head H2 at the inner end thereof, and also includes a head H3 at the outer or forward end thereof.

The head H3 is formed with a forwardly projecting ball socket II4 within which a ball pivot member II5 rotatably engages. The pivot mem-- ber I I5 includes a shank I I6 which extends downwardly into a bushing II'I carried by the head or top member 55. The socket member 4 is formed with upwardly offset boss I|8 having a slot II9 within which a pin I26 extending upwardly from the ball II5, loosely engages. The pin I20 cooperates with the slot 9 in the boss II8 in holding the head II3 against rotation about a horizontal axis.

The head II3, which is the suction head, has extending downwardly therefrom a pipe I2I which extends downwardly through a tube I22 carried by the top wall I23 of the tank 5|. The tube |2I extends to substantially the bottom of the tank 5| and is formed with a bushing I24 having a suction head disposed therein, of conventional construction.

The cylinder III of the pump is sealingly secured in the heads H2 and H3 by means of a pair of bolts I25 engaging through ears I26 and I2'I carried by the heads I I2 and I I3 respectively. The ends of the cylinder I I I bear against a compressible sealing gasket I28 which may be in the" form of a lead gasket or the like so that the cylinder III will be tightly disposed within the heads H2 and IIB. The head II2 has secured thereto a dome I29 which is formed with a pair of outlet nipples I 30 with which a pair of flexible tubes I3I are connected.

A spraying boom generally designated as I32 is mounted on the forward end of the machine and includes a vertically disposed pipe I33 which is secured by clamping members I3 3 to a supportingbracket generally designated as I35. Ihe bracket I35 includes a lower arcuate bar I35 and a pair of upwardly convergent bars I51. The pipe I33 has interposed in the length thereofa coupling I38 and a pair of laterally extending nipples I39 are carried by the coupling I38 and the forward ends of the tubes or hose members Edi are connected with the nipples IBd.

The pipe I33 has secured to the upper end thereof a pair of horizontally projecting branch pipes Itil which are secured at their inner ends to anupper coupling Edi fixed on the upperend pf thepipe I33. Theouter ends of the branches Hill are bent forwardly asindicated at I 32, and spray. nozzles I453 arecarried by the outer ends of the branches IE5. These spray nozzles I53 are herein shown as being downwardly directed, butpit willbe understood thatthey may be adjusted through adjustment of the couplings M 3 carried by the outer ends of the branches M5, to discharge the insecticide at any desired angle relative to the vertical.

The coupling L38 has secured thereto a pair of longitudinally curved branch pipes M and the branch pipes I 35 have secured to the upper ends thereof spray nozzles Hit. A pair of lower branch pipes I41 are secured to a lower coupling Ids carried by the lower end of the vertical pipe I33 and a pair of spray nozzles I65 are mounted on the outer ends of the pipes Isl. An additional pair of branch pipes I55 are secured to the intermediate lower coupling I5l carried by the pipe I33, and spray nozzles I52 are secured to the outer ends of the branch pipes I55.

The tank 5| has mounted in the top thereof a funnel I53 which engages in an opening I5d formed in the top wall I23 of the tank 51. The dome I29 includes a downwardly directed valved return nipple I55 for discharging excess insecticide into the funnel I53 for return to the tank 5!.

Referring now to Figures 9 and 10, there is disclosed a modified form of spraying boom which includes a supporting pipe or tube I55 which is fixed by clamping members I5? to a pair of upwardly extending brackets I53. The brackets I58 are carried by clamping means I59 secured by fastening members I638 to the handles 3d at a point to the rear of the tank 5I. A pair of inverted U-shaped pipes ISI are disposed one on each side of the machine, and each pipe It! includes a coupling I62 having fixed thereto an elongated rod I63 which engages in the adjacent end of the supporting tube I53.

The rod I53 is fixed in adjusted position by means of a set screw Itd threaded through a collar I65 and threaded also through the tube I55. The pipe I5! has fixed thereto a pair of lower spray nozzles I66 which are inwardly directed, and an intermediate pair of nozzles I61 are secured to the vertical legs I58 of the pipe I5! above the nozzles I65. The nozzles as: are secured to a 45 coupling use so that these nozzles IE1 may be angularly adjusted to direct the spray either inwardly in a horizontal direction or at any desired inclination to the vertical. This inclination may be either upwardly or downwardly.

The upper spray nozzle I152 is carried by the coupling IE2 and is adapted to direct the insecticide downwardly between the nozzles I68 and I61. The coupling I52 includes a rearwardly projecting nipple I1I which isadaptedto' bacon;- nected by a hose H2 to the discharge-side of :the

pump.

Referring now to Figures 17 and 13,:there is disclosed a another modified form of spraying boom embodying three spray nozzles .for each side of the machine. .An inverted.U-shaped pipe I'I3. has a pair of confronting spray nozzles. II i mounted on the lower endsof the parallel legs.

I15 thereof, and a coupling I16 is secured to the bight Hi1 of the pipe I15, and an upper. downwardly directed spray nozzle I18 is carried by. the.

coupling I15. The coupling I16 includes ahorizontally disposed supporting rod I15 whichis engageable in the adjacent end of the horizontal supporting tube 155 and secured in adjustedv position by means of a setscrew Ifi l. As shown. in Figure 18, the lower. ends of thevertical legs I15 are forwardly bent as indicated at. I80, so as,..t o offset the lower nozzles I'I i forwardly from the upper nozzle I13.

Referring now to Figures 19 and 20, there is disclosed another form of spray structure embodying a longitudinally bowed pipe [8| having a coupling I32 between the ends thereof. The longitudinally bowed pipe I8I is formed with forwardly projecting opposite ends I83 on which couplings Hid are secured, and spray nozzles I85 are secured to the couplings I85. The couplings its may be angularly adjusted so that the spray from the nozzles I85 may be directed either downwardly and inwardly or at any other inclination to the vertical. An intermediate or upper and downwardly directed nozzle I85 is carried by the coupling I82 for directing spray downwardly between the nozzle I85. A supporting rod 581 is fixed to the coupling I82 and is adapted to be adjustably secured to a supporting tube I56 as shown in Figure 9.

In the use and operation of this spraying machine the frame 25 may have connected therewith a tractor means such as a horse or tractor. The tank 5! may be filled through the opening I54 and as the machine moves between a pair of rows of plants such as tobacco, cotton or the ike, rotation of the wheels 36 will effect operation of the pump with the pump cylinder III swinging or oscillating on the pivot member H5 as the piston IE0 is reciprocated by means of the rotating crank I54. The pump III may be of such capacity that an excess of liquid will be pumped and this excess of liquid will be returned to the tank 5I by the return pipe I55 discharging into the funnel I531.

By roviding different types of spraying booms the plants may be sprayed on both the under and upper sides thereof, and this spraying process may progress with the growth of the plant. As the plant grows taller the different spraying booms herein disclosed may be used so that the insects which are killed by contact will be properly sprayed in the different stages of the plant growth.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.

What I claim is:

In a machine of the character described, a casing with a horizontal shaft operatively connected with a vertical pump shaft therein, hearing bushings engaging about said horizontal shaft, and a pair of anti-friction roller bearings mounted in said bushings, said bushings formed at their inner ends with an annular flange against which the inner ends of said roller bearings engage and a counterbore at the outer ends of said bushings within which a. sealing member is mounted, with a metal washer interposed between the sealing member and the outer end of said roller bearings. each of said bearing bushings having an upwardly projecting lug secured to fixed external fastening means, a pair of collars engaging about said horizontal shaft and bearing at their outer sides against the inner ends of the bearing bushings to hold said horizontal shaft against endwise movement relative to the bearing bushings, said casing formed with flanges at its outer ends which engage annular grooves formed in the bearing bushings and an upwardly projecting bushing formed on said casing within which the reduced lower end of the bushing, rotatively supporting the vertical pump shaft, engages.
